The Dominant Scale is the same as series of notes as the Mixolydian scale. It is also the same series as the Major scale, except the seventh note is lowered a half step. This scale works well over the dominant seventh (e.g. C7, G7, A7, etc).
1 W 2 W 3 H 4 W 5 W 6 H b7 W 1
Examples:
C Dominant = C D E F G A Bb C (Play over C7)
F Dominant = F G A Bb C D Eb F (Play over F7)
A Dominant = A B C# D E F# G A (Play over A7)
